Dragonbane – Can be obtained in Sky Haven Temple during the quest "Alduin's Wall" – It is located on a table in an atrium just off to the left of the main chamber. Best version is available at or above level 46.

A leveled item will use the base stats from when the Dragonborn first enters the item's location. If the Dragonborn does not collect the item and leaves, the base stats will remain the same as when the area was first entered, regardless of the Dragonborn's level when returning and claiming the item.

e.g. The Dragonborn enters the Riftweald Manor at Level 12, but chooses not to take Chillrend as this will overburden him/her. The Dragonborn continues his/her adventures, returning to Riftweald Manor at level 27. Despite the Dragonborn's level being 27, the base stats had previously been set to level 11–18.
